NAME
       mitem_userptr - associate application data with a menu item

SYNOPSIS
       #include <menu.h>
       int set_item_userptr(ITEM *item, void *userptr);
       void *item_userptr(const ITEM *item);

DESCRIPTION
       Every  menu  item has a field that can be used to hold application-specific data (that is,
       the menu-driver code leaves it alone).  These functions get and set that field.

RETURN VALUE
       Except for item_userptr (which returns NULL on error), each function returns  one  of  the
       following:

       E_OK The routine succeeded.

       E_SYSTEM_ERROR
	    System error occurred (see errno).

SEE ALSO
       curses(3X), menu(3X).

NOTES
       The header file <menu.h> automatically includes the header file <curses.h>.

PORTABILITY
       These routines emulate the System V menu library.  They were not supported on Version 7 or
       BSD versions.

       The user pointer should be a void pointer.  We leave it as a char pointer for SVr4 compat-
       ibility.
